In vivo dynamics of innate immune sentinels in the CNS

D Nayak, BH Zinselmeyer, KN Corps, DB McGavern - Intravital, 2012 - Taylor & Francis
The innate immune system is comprised of cellular sentinels that often serve as the first
responders to injury and invading pathogens. Our basic understanding of innate immunity is …

Inverse synaptic tagging of inactive synapses via dynamic interaction of Arc/Arg3. 1 with CaMKIIβ

Functional anatomy of neural circuits regulating fear and extinction

E Knapska, M Macias, M Mikosz… - Proceedings of the …, 2012 - National Acad Sciences
The memory of fear extinction is context dependent: fear that is suppressed in one context
readily renews in another. Understanding of the underlying neuronal circuits is, therefore, of …
